James 2:1-4
How can you claim to have faith in our glorious Lord Jesus Christ if you favor some people over others? … If you give special attention and a good seat to the rich person, but you say to the poor one, ‘You can stand over there, or else sit on the floor’—well, doesn’t this discrimination show that your judgments are guided by evil motives?

Matthew 25:41-45
Then shall he say also unto them on the left hand, Depart from me, ye cursed, into everlasting fire, prepared for the devil and his angels: for I was an hungred, and ye gave me no meat: I was thirsty, and ye gave me no drink: I was a stranger, and ye took me not in: naked, and ye clothed me not: sick, and in prison, and ye visited me not. Then shall they also answer him, saying, Lord, when saw we thee an hungred, or athirst, or a stranger, or naked, or sick, or in prison, and did not minister unto thee? Then shall he answer them, saying, Verily I say unto you, Inasmuch as ye did it not to one of the least of these, ye did it not to me.

Zechariah 7:9-10
Thus says the Lord of hosts: Render true judgments, show kindness and mercy to one another; do not oppress the widow, the orphan, the alien, or the poor; and do not devise evil in your hearts against one another.

Leviticus 19:34
The alien who resides with you shall be to you as the citizen among you; you shall love the alien as yourself, for you were aliens in the land of Egypt: I am the Lord your God.

Deuteronomy 27:19
‘Cursed is anyone who withholds justice from the foreigner, the fatherless or the widow.’ Then all the people shall say, ‘Amen!’
